Figure ,.7 is v, an enlarged, fragmentary detail horizontal sectional view, illustrating the arf- `rangenfientrof the snap head yor button on the conduit tubeutilized in the modified form of our `letter P generally. indicates one ,preferred form of the smoking pipe, kand as illustrated, the same includes a pipe bowl Il), havingA rformed integral therewith; a stem Il. The bowl is provided with the usual tobacco receiving compartment I2, but

lit .is tobe noted/that in accordance with the invention, the compartment I2.` terminates short of the lewerend of the bowl. Extending into the lower endof the bowl at the axial center thereof `.is ashort lengthoi tubing I3, closed at its lower end, `as lat I4. -The eXtreme lower end ofgthe tubing is provided with-.an outlet port I5, the walls of which are curved to provide a ball seat, ya's'will be later set forth. It is to ben-oted, however, that this shortv length of tubing I3 closed `at-.its bottom, will serve asa chamber for the collection of liquid matter and hence this `tubing .will preventthis matter from collecting in the bottom ofvv the bowl. yThe stem I I `is slotted as -at l,- from its extreme rear endto the short length of tubing and such-slot lopens out through the vlmfverend of the stem.; The. bottom portions of Athe stem on each side ofthe slot I6 are preferably fiattened, asat I'I, forapurpose which will i be laterset forth. l

V.-..Associated with the stem in a .novel manner is abit I8-formedfrorn any desired material, and the outerfendof the .bit isformed to proffide-a mouth piecevl. `Rigidly securedto the bit and communicating with the longitudinal bore thereof, is a smoke conduit tube 2|. This tube 2| in connection with the bit and stem forms a vital part of this invention. The tube can be constructed from any desired type of material such as aluminum. The tube 2| extends from the inner end of the bit to the short length of tubing I3 and is normally received within the slot i5 of the stem, as can be seen by referring to Figures l and 2. The extreme forward end of the tube is shaped to provide a substantially ball shaped head 22, which is adapted to snugly t within the port I5 of the tubing I3.

In accordance with the invention, a block 23 is received within the slot |6 at the rear end of the stem and the block is pivotally connected to the stem for swinging movement by pivot pins 24 which extend through the sides of the stem and into the block. The block is provided with a longitudinally Vextending guide way 25, which slidably receives and supports the tube 2 I.

By this construction, so far, it can be seen that the bit I8 and the tube 2| can be slid longitudinally relative to the stem and can be swung on said stem to the dotted line position shown in Figure l, as will be hereinafter more fully set forth.

An expansion spring is coiled about the tube 2| and is coniined between the block 23 and a collar 21 on the tube and hence the tube and the bit are normally urged toward the bowl. When the bit IB and the tube 2i are in their normal position as shown in full lines in Figures l and 2, the ball head 22 will be held in firm contact with the walls of the port l5 and hence accidental swinging movement of the bit and the tube will be prevented and fluid tight communication will be established between the bowl and the bit.

After the smoking of the pipe, and when it is desired to clean the same, it is merely necessary to pull back on the bit I8 against tension of the coil spring, so as to unseat the head 22 from the tubing |3 and the bit and tubing can now be swung at an angle to the stem, as shown in Figure l. By blowing through the bit, the bit and stem can be readily cleaned and if so desired, a pipe cleaner can now be easily passed through the bit and stem. To return the bit and tube to their normal positions, it is merely necessary to swing down on the bit and pull the same rearwardly until the tube is again moved into the stem, at which time the bit can be released. While it is preferred to pull back on the bit, to swing the stem, obviously the tube can snap into and out of position upon forcible swinging of the bit.

Attention is directed to the fact that the tube 2| is spaced from the walls dening the slot I6 and this permits circulation of air around the tube to cool the smoke. If desired, the outer surface of the tube can be provided with heat radiating fins 23. One method of forming these ns is to provide a screw thread around the outer surface of the tube.

The outer end of the bit h3 is slightly angled, as can be seen by referring to Figure l, and owing to the iiattened portions |l' of the stern, the pipe can be readily laid on a iiat surface in an upright position with the mouth piece disposed above said surface. This keeps the mouth piece in a sanitary condition.

In Figures 5 to '7, inclusive, is shown a slightly modied form of the pipe and this form is indicated by the reference character S.

rl`he pipe S includes the bowl 29, having the tobacco receiving chamber or compartment Sil, with which communicates the short length of tubing 3|. The tubing 3l is of identically the same character as the tubing I3 and the tubing 3| is provided with a port 32 having its walls curved or beveled to form a ball seat. Extending laterally from the bowl 29 is a stem 33 and the stem is provided with a longitudinally extending slot 34, opening out through the bottom thereof. The slot extends from the tubing 3| to the rear end of the stem. Disposed in the slot is a swinging block 35 which corresponds to the block 23 and this block is pivoted to the stem by means of pivot pins 38. Normally disposed in the slot 34 is a smoke conduit tube 31 and this tube, in this form is rigidly fastened to the block and extends therethrough for rigid connection with the bit Bil. Slidably mounted in the extreme forward end of the tube, is a hollow head 39 and this head is normally urged toward the bowl by an expansion spring 4B. The outer end of the head is curved so as to ht snugly within the port 32.

In this form of the pipe, by swinging the bit,

`the head can be snapped into and out oi engagement with the wall of the port and hence the pulling back ci the bit 3S is eliminated.

If preferred, a finishing strip :il can be cured to the block 35 for swinging movement with the bit and tube el, and when the bit and the tube are in their normal position, this iinishing strip 4| will close the slot 34.

The circulation of air around the tube 3l is iacilitated by providing the stem with a series of longitudinally extending narrow vent slits Q2. The tube may or may not be provided with heat radiating hns. In the form of the invention shown in Figures 5 to 7, the pipe can be cleaned in the same manner as the pipe illustrated in the preferred form and hence the bit and tube can be swung at an angle to the stem for cleaning purposes.

Changes in details may be made without departing from the spirit or the scope of the invention but what we claim as new is:
